The combined situation

Nudify.online is a freemium nudify service that allows three free outputs per day per IP. The pay tier removes watermarking and increases output resolution. When Nudify.online output appears on 4chan, removal proceeds through the statutory takedown process under 47 USC 223a combined with source attribution to strengthen the legal claim.

Why this combination is high risk

Nudify.online has no terms of service, no contact information, and no age verification. The service is accessible from school networks in most United States districts because it has not been added to standard content filtering blocklists. On 4chan specifically, 4chan boards including /b/ and /soc/ have historically been primary distribution points for ncii. threads expire quickly but content is preserved in third party archives that mirror entire boards.

How removal proceeds

4chan threads expire automatically. Active removal requires emailing dmca@4chan.org with the thread URL. Archive sites such as warosu and archive.4plebs require separate filings. Source attribution to Nudify.online is documented through free tier outputs carry a faint nudify watermark in the lower right corner, which strengthens the takedown notice and supports parallel legal action.
